Oximeter probes tuaj yeem muab tso rau ntawm preductal ( sab tes xis ) thiab postductal (ko taw) qhov chaw los ntsuas rau txoj cai -to-sab laug shunting ntawm qib ntawm foramen ovale thiab ductus arteriosus.
Ib yam li ntawd, koj tuaj yeem nug, yog sab laug tes ua ntej lossis tom qab ductal?
Txoj cai Tes - Sab Tes Peb xaus los ntawm peb cov ntaub ntawv uas perfusion ntawm lub sab laug tes tsis muaj kev cuam tshuam los ntawm cov hlab ntsha hauv lub cev thiab tuaj yeem txiav txim siab tau ua ntej - cev . Nyob rau hauv pawg sub uas muaj cov menyuam mos uas muaj kev ua pa tsis zoo, ib qho kev sib txawv, tab sis tsis muaj qhov sib txawv tseem ceeb ntawm ob qho tib si. tes tau kuaj pom (p-tus nqi 0.06).
Kuj Paub, yuav tsum Preductal SATS siab dua Postductal? Yog tias preductal saturation yog siab tshaj cov tom qab satura- tion, sib txawv cyanosis tshwm sim, uas tshwm sim thaum muaj ib txwm cuam tshuam txog cov hlab ntsha loj thiab deoxygenated ntshav los ntawm cov hlab ntshav sib kis nkag mus rau aorta nqis los ntawm txoj cai patent ductus arteriosus.
Tom qab ntawd, lo lus nug yog, Preductal thiab Postductal saturation ntsuas li cas?
Ib txoj hauv kev yooj yim txhawm rau txheeb xyuas txoj cai-rau-sab laug shunting yog siv ob lub mem tes oximeters thiab ntsuas preductal thiab postductal Spo2. Hauv ib txoj kev tshawb fawb15 nws pom tias arterial saturation hauv sab caj npab ( ua ntej tsawg kawg 3%saum toj saud ( tom qab ) yog pov thawj ntawm txoj cai-rau-sab laug ductal shunting.
Pre thiab post ductal SpO2 yog dab tsi?
Ua ntej - ductal thiab ncej - cev O2 saturation nyob rau lub sijhawm noj qab nyob zoo thaum yug los. Hauv 5 feeb, qhov nruab nrab ua ntej - Lub cev SpO2 qib yog 89% (7), thiab qhov nruab nrab ncej - Lub cev SpO2 qib yog 81% (10). Ua ntej thiab tshaj tawm - Lub cev SpO2 qib sib txawv heev thaum thawj 15 feeb tom qab yug me nyuam.
